Definitions

  • the present invention relates to a method and a device for extracting intermediate flat supports for stacks of products in accordance with the preamble of claims 1 and 5.
  • the invention relates to a method for extracting intermediate flat supports for stacks of cardboard cutouts arranged on pallets and the like.
  • stacks of cutouts such as for example those used to package cigarette packets of the rigid flip-top type.
  • These stacks of cutouts are generally arranged on a pallet-like support in multiple rows and in a plurality of layers that are separated from one another, in pairs, by an intermediate flat support constituted for example by a sheet of paper of appropriate thickness.
  • These devices pick up the stacks of cutouts in an orderly fashion and then transfer them to an inlet of a user machine.
  • Said grip means are capable of moving between a position for picking up the intermediate flat supports and a position for releasing said intermediate flat supports inside a collecting container.
  • the suction of the suckers also affects the cutouts that are arranged at the regions where said suckers are applied.
  • the lifting of the flat support tends to produce, with known extraction devices, movement of the cutouts located at the top of the stacks with respect to the lower ones, due to adhesion between said flat support and said cutouts.
  • the aim of the present invention is to provide an extraction method and a device that allow to eliminate the above described drawback, extracting the intermediate flat supports without interfering with the stacks of products.
  • a method and a device are provided for extracting intermediate flat supports of stacks of products, as defined by the combinations of steps and features of claims 1 and 5.
  • the step of moving said element above said flat support to be extracted is performed by moving said suction means into contact with said flat support.
  • the reference numeral 1 designates a device for extracting intermediate flat supports 2 for stacks 3 of cutouts, such as for example those used to package cigarette packets of the rigid type.
  • the stacks 3 of cutouts are arranged in an orderly fashion on pallet-like supporting means 4.
  • the stacks 3 of cutouts are arranged so as to form superimposed layers 5 that are mutually separated by virtue of the intermediate flat supports 2, which are made of flexible material, for example paper.
  • the extraction device 1 includes a vertical framework 6 that is provided with a container 7 for collecting the extracted flat supports 2.
  • Said framework 6 is provided, in a substantially median position, with a bracket 8, and an arm 10 that oscillates on a vertical plane is pivoted to said bracket 8 by virtue of a pivot 9 that has a horizontal axis.
  • the arm 10 is suitable to be actuated, by means of a crank 11, by a jack 12 that is pivoted to said framework 6.
  • a grip element 14 is articulated to the free end of the oscillating arm 10 by means of a pivot 13 having a horizontal axis.
  • Said grip element 14 comprises a frame 15 provided with suction means 16 that are constituted for example by a plurality of suckers 16 adapted to be connected to appropriate known suction devices, which are not shown in the figure.
  • the grip element 14 is furthermore provided, on the same side as the suckers 16, with a plurality of presser elements 17 that are actuatable by respective actuators 18 along axes that are perpendicular to the frame 15.
  • the suckers 16 are arranged at opposite ends of the frame 15, so as to act at the peripheral region of the flat support 2 to be extracted, while the pressers 17 are arranged in a central region of said frame 15.
  • the method for extracting the intermediate flat supports 2 entails a first step during which, by rotating the oscillating arm 10, actuated by the jack 12, the frame 15 is placed above the flat support 2 to be extracted so that the suckers 16 are arranged in contact with said flat support 2.
  • presser elements 17 are actuated by the actuators 18. Said pressers 17 act on the stacks 3 that lie below the flat support 2 to be extracted, by virtue of the interposition of said flat support 2, in order to apply a constant pressure that is directed towards the pallet 4 and is capable of blocking said stacks 3.
